附加资料：
下载该组件后，按如下示例编写代码即可实现php在线发送邮件．
  一：前台表单
phpmailer Unit Test
请你输入收信的邮箱地址:
邮箱地址:
二：后台PHP程序
IsSMTP(); // 使用SMTP方式发送
$mail->Host = "mail.xxxxx.com"; // 您的企业邮局域名
$mail->SMTPAuth = true; // 启用SMTP验证功能
$mail->Username = "[email protected]"; // 邮局用户名(请填写完整的email地址)
$mail->Password = "******"; // 邮局密码
$mail->From = "[email protected]"; //邮件发送者email地址
$mail->FromName = "您的名称";
$mail->AddAddress("$address", "");//收件人地址，可以替换成任何想要接收邮件的email信箱,格式是AddAddress("收件人email","收件人姓名")
//$mail->AddReplyTo("", "");
//$mail->AddAttachment("/var/tmp/file.tar.gz"); // 添加附件
//$mail->IsHTML(true); // set email format to HTML //是否使用HTML格式
$mail->Subject = "PHPMailer测试邮件"; //邮件标题
$mail->Body = "Hello,这是测试邮件"; //邮件内容
$mail->AltBody = "This is the body in plain text for non-HTML mail clients"; //附加信息，可以省略
if(!$mail->Send())
{
echo "邮件发送失败. ";
echo "错误原因: " . $mail->ErrorInfo;
exit;
}
echo "邮件发送成功";
